What is this class

 

It is not a pipe but oil paint on canvas.

René Magritte was a surrealist painter that encouraged the viewer to use their free mind to explore the logical shortcuts that human take when viewing items and instead to encourage alternative thinking about what is in front of you.

Data Analysis

 

Why R?

 

What is R?

R is a language for data analysis and manipulation.

  • Based upon S-Plus (Bell Laboratories).
  • Open Source.
  • Collaborative.
  • Community Supported.

Challenges

Some of the challenges that I’ve seen individuals face when learning something like R.

  • This is not a point-and-click experience.
  • You will have to learn a grammar.
  • CASE SENSITIVITY MATTERS!

Benefits

There are several benefits to larning a general purpose analysis framework.

  • No vendor lock-in.
  • Data are data.
  • Transferable skills to other disciplines/problems/issues.

Today’s Activities

To Do Right Now!

First things first! We need to get everyone configured to have the most up-to-date versions of the software and libraries we are going to start with on this class.

Install R onto your laptop (version 4.2+).

Install RStudio—the “One True Interface” (2022.07.1+554 or later).

Install Quarto to help make dynamic documents, webpages, sites, and reports (1.0.38 or later)

Install Packages that we’ll start with (and get a peek at Github).

Getting Additional Integration

Let’s let quarto install a few additional things on your machine. Switch over to the terminal in RStudio and type the following (for TeX)

quarto install tool tinytex

And if you do not have a version of Chrome on your laptop, also hit this one to aid in rendering images for pdf and docx files.

quarto install tool chromium

Loading Default Libraries

I’ve set up a file for you to source to install
